No. 95,667, Patent-ed Oct. 12,1869.

' UNITE STATES PATENT OFFICE.

EDWARD DITHRIDGE, OF PITTSBURG, PENNSYLVANIA.-

LAMP-CHIMNEY.

Specification forming part of Letters Patent No. 95,667, dated October12, 1869.

To all whom it may concern:

Be it known that I, EDWARD DITHRIDGE, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Lamp-Chimneys; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification, in which-Figure 1 represents a central vertical section of my lamp-chimney. Fig.2 is'a side elevation of the same.

The nature of my invention consists in the construction of alamp-chimney, the base of which is rounded and welted in the manner setforth.

A represents the form of my chimney, and B the welt around the base.

The welt B is formed by reheating that portion of said chimney anddoubling it over so as to form said welt; By this process the base ofthe chimney is made thicker, and thereby its strength is increased, andit is less liable to chip off than the base of chimneys of the ordinaryconstruction. Having thus described my invention, what I claim as new,and desire to secure by Letters Patent as a new article of manufacture,is-

The within described lamp -chimney, its lower end or base being turnedover and welted, substantially as set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

EDWD. DITHRIDGE.
